Title: Pre-activated flowing-water detector
Inventor: CHIBA RYOTARO
IPC: A62C35/62
Filed: 2001-04-26
Abstract: PROBLEM TO BE SOLVED: To drain fire-extinguishing water which fills up secondary-side piping due to false information given by a fire detector without any complicated operation. SOLUTION: Each time a fire-detector gives an erroneous alarm, the valve concerned closed, the fire-extinguishing water fills up in the secondary-side piping. Even though a starting valve is closed, the water still remains and may cause a leaking damage and/or freezing, which may also lead to an impairment of a function of pre-activation of a flowing-water detector. Therefore in such a case, the water has to be drained by a manual operation. An orifice 50 in a secondary side 4 of the flowing-water detector being provided, the fire- extinguishing water filled up in the secondary side 4 is automatically drained by closing of a starting valve 17 when the fire alarm turns out to be false.
